' Application led October 4, 1927. Serial No. 224,005.

This invention relates to boot and shoe jacks upon which boots or shoes are inverted and placed for the purpose of holding the Vshoe during vmany ot the diiterent operations in making or repairing.

Y Thegeneral object of the present invention is to provide ajack ot this Character having a standard supporting the last or other element upon which the shoe is placed, lo which standard is mounted for rotation around a vertical axis and upon a base or mounted for oscillation in aY vertical plane, this oscillatory movement, however, also permitting the base of the ack to be rotated so that the standard in aninclined position may be rotated around a vertical axis.

A further object is to provide a jack of this character which is adjustable into many different positions and my improved ack is, as a matter of tact, adjustable into about fifty-six diiierent positions.

A still further object is to provide a device of this character which may be adjusted so as to compensate for wear and which is simple, strong and effective in actual use.

. Other objects will appeargin the course of the following description. n j

abase plate having the legs 11, these legs being `disposed in any suitable manner. The base plateis formed integral with an upwardly extending annular member l12 formed adjacent its upper end lwith a circum- Figure 8 is an elevation of one of the .i

Referring to these drawings, 10 designates ferential recess 13. Surrounding thisv annular member 12 is a second annular member 14 having one or more set screws 15 which extend into the recess 13 and permit the annular member or sleeve 14 to be rotated around the member 12. y

Mounted upon the member14 by screws 16 is a supporting bracket 17 the upper end of which is vertically slotted or biturcated, as at 18, and crossing this sletted portion is the transverse pin 19 constituting a pivot pin. The inner face of the plate or-bracket17 is recessed, as at 2O,y this recess accommodating the cylinder 14.` Pivotally mounted upon the bracket 17 is a cylinder 21 which is adapted toy align with and seat upon cylinder 14. Thiscylinder 21 carries the sector 22 through which the pivot pin 19 passes, andthe sector is formed with a plurality of pertorations 23 arranged in a series concentric to the pivot 19 into which a springprojected lockingpin 24 engages, this locking pin being mounted upon and carried by the bracket 17 having a head 25 whereby the locking pin may be retracted against the action ot the spring' 26. By this means the cylinder 2l .may be supported upon the bracket in any desired angular-position.

Disposed within the cylinder 21 is a. cy-

lindrical section 27 having a head 28 which extends over vthe upper end of the cylinder 21 and ist'ormed with a series of spaced bolt-receiving apertures 29 yfor engagement by a sliding' bolt -30 mounted in the upper end ol" thcwcb or sector 22 and projected by means of the spring 31. This bolt has the head 32 whereby it may be retracted. This spring is held in place by the pla-te 33 at# tachcd by screws or other suitable means to the sector web 22.- The cylindrical member 27 adjacent its. lower end is formed with a circumferential groove 34 and cylinder 21 is formed with one or more set screws 35 extending into this recess soVA that the cylindrical member `27 may-be rotated around its axis but cannot be pulled out.

The member 27 does `not extend down lthrough the full depth 'of the cylinder 21 and is provided with the'many-sided taperl ing bore j or ksocket 36 within which the tapering lower end of a standard 37 is disposed. The upper end of this standard carries the metallic or other last 38. It will be understood that the cylindrical member 14 is rotatable around the cylinder 12, which ot the cylinder 14. Whenthi's latch is de pressed out ot any one 01"' Vthese notches 42, the cylinder 14 may be rotated, carrying with it the bracket 17, and the structure supporting the standard 37 and the last.

For the purpose of depressing this latch 40, I provide the depending rod 43, which atits lower end is connected to a treadle llt pivotally mounted in brackets 45 on the floor. By this means the workman can at any time release the latch 40 and then turn the cylinder lll to carry the shoe into any desired position. By pulling out the latch or bolt 24, the upper section may be oscillated in a 'vertical plane to dispose the standard at any desired angle. By pulling out the bolt 30, the cylindrical base member 27 'for the standard may be rotated around the longitudinal. axis of the standard so as to rotate the shoe around this Thus it will be seen that with the construction described a large number of di'li'erent adjustment-s may be made, cach adjustment being independent of any other adjustment, so that the work may be presented in the best possible fashion to the workman. As a matter of fact, and as before stated, there are some titty-six different positions into which the standard as a whole may be adjusted.

In Figure 7, I illustrate another iorm of bracket 10a. rIhis praoket 10L has approximately the same form as the bracket 17 and is formed with a slot 18a and a transverse pin 19, but in place of the latch bolt 2a there is provided a pivoted latch 4G pivotn ally mounted in a slot 47upon a pin 48 and having the depending portion 49 engaged by a coiled contractile spring 50 which urges the latch upward. The latch has a. portion 51 adapted to engage in transverse recesses or teeth formed in the sector 22 and the latch is extended laterally so as to 'torni a Ithumb piece 52. Al stop 53 limits the downward movement of the latch.

The operation of the general mechanism is the same whether the latch means shown in Figure 7 be used or the latching bolt 2e be used. A stand constructed in accordance with my invention may be made for a considerably less sum than the ordinary ack or stand and gives better and quicker results at a lower cost. The stand completed weighs about titty-live pounds and this is about onehalf the weight of ordinary stands. The adjustments may be made with a minimum of effortand time and the parts which are likely to wear down can be adjusted by adjusting six set screws. No dirt can enter the stand for the reason that the interior parts are thoroughly protected. It any dirt should drop into the interior ot the cylinder l2, it will pass through onto the floor. Y

It will be obvious that many modiiic'ations might be made in the details of construction and arrangement ot parts without departing from the spirit of the invention as defined in the appended claims.
